Its chief object is to Patented Dec. 8, 1931 UNITED. STATES PATENTOFFICE JOHN A. s'rocnux AND HAIRY SWERDLOH, OF BUFFALO, NEW YORK nnmxoOPERATING DEVICE FOR AUTOMOBILES Application filed Kay 2, 1928. SerialNo. 358,818.

This invention relates to an electrically operated device or motor whichhas been designed more particularly for raising and lowering the Windowsof automobiles.

provide a device of this character which is simple, compact andinexpensive in construction, and which will instantaneously effect theraising or lowering of the window by the closing of a switch.

Other features of the invention reside in the construction andarrangement of parts hereinafter described and particularly pointed outin the appended claims.

In the accompanying drawings Figure 1 is a sectional view of anautomobile body showing my invention applied thereto. Figure 2 is anenlarged transverse, vertical section of the device. Figure 3 is avertical section taken in the plane of line 33, Figure 2. Figure 4 is adiagrammatic view of the motor and the circuit. Figure 5 is a face viewof an automobile door showing the operative mechanism for raising andlowering the window.

Similar characters of reference indicate corresponding parts throughoutthe several views.

By way of example, our invention has been shown applied to anautomobile-body 10 in connection with the operating mechanism forraising and lowering the windows 11 thereof, the numeral 12 indicatingthe customary shaft or spindle of such mechanism. Mounted on the spindleis a pinion 12' meshing with a gear 12 and connected to the latter is anarm 12 provided at its outer end with a stud 12 guided in a horizontalslot 12 formed in a plate 12 to which the lower edge of the window 11 isanchored. The present device is adapted to be readily mounted on thebody or doors thereof in operative rela tion to the window-elevatingmechanism. To apply our device, it is only necessary to remove theoperating handle ordinarily employed for manually actuatin the windowand substitute the device there or.

The improved device is preferably in the form of a reversible electricmotor, consist ing of a substantially bowl-shaped, shallow casing orshell 13 whose open rear face 14 is adapted to rest flatwise against thebod or door of the car over the operating spindfe 12 of thewindow-elevating mechanism and which has a plurality of radial attachingears 15 for securing the same in place by bolts 16 or similarfastenings. To insure a uniform and even bearing of the casing on theupholstered body of the car, an insulating attachin spider 17 is appliedto its rear side and he d in place by the bolts 16. The front side ofthe casing has a threaded opening 18 in which is removably arranged acombined closure and bearing-plate 19. Journaled at one end in bearings20 in this plate is the motor-shaft 21 whlch is supported at its0pposite end in the spider 17. The outer or rear end of the motor-shafthas a socket for receiving the spindle 12 which is coupled thereto y aset screw 22.

Secured to the inner wall of the casing 13 are pole pieces 23 containingthe usual coils or windings 24 and mounted on the shaft 21 is anarmature core 25 having a plurality of radial notches 26 at itsperiphery for receiving the windings (not shown) of the armature. Asshown in Figure 2 the inner or rear face of the armature core ispreferably recessed in concave fashion, as indicated at 27, about themotor shaft to receive the windings of the armature. Attached to thefront face of the latter is a fiber disk 28 containing a plurality ofcommutator segments 29 secured thereto by bolts 30 and preferablyprovided with radial, outwardly-opening notches 31 to receive thefastening ends of the armature-windings. A spacing sleeve 32 may beinterposed between the rear side of the armature core and the spider 17to hold the armature against the brushes to be presentl described.

ounted on the inner side of the combined closure and bearing plate 19 isa fiber holder in the form of a disk 33 to which are secured the copperbrushes 34 adapted to traverse the commutator se ements 29.

The motor circuit is illustrated diagrammatically in Figure 4, 35 and 36indicating the positive and negative leads, respectively, 37 the wiresleading from the coils 24 of the pole pieces 23, and 38 the wiresleading from 1 the armature to the reversing switch 39 having thecontacts 40, 41, and 42. When the switch engages the contacts 40, 41 themotor travels in a direction to open the window of the car to anyposition desired and when the switch is engaged with the companion pairof contacts 41, 42 the direction of the motor is reversed and the windowis accordingly closed. The duration of the closed position of the switchwill automaticall govern the degree of movement of the win ow in eitherdirection.

The closure 19 is provided in its outer face with a well or cavity 43for receiving an emergency foldable hand crank 44 connected to the motorshaft 21 and whereby the latter may be actuated to manually operate thewindow in the event that the motor fails to act. A screw-cap 45 isfitted over the closure to normallly conceal the hand crank.

While manifestly simple and compact in construction, this improveddevice provides for the automatic raising and lowering of the windows ofan automobile by the mere act of closing a switch; itis so organizedthat it can be readily applied to the automobile and re-.

quires but a minimum of space; and its construction is such that itsparts are easily accessible by removal of the closure 19 to efi'ectadjustment, inspection or repair.

We claim as our invention 1. An electric. window-operating device forautomobiles, comprising a reversible motor including a shaft adapted foroperative connection to the actuating spindle of the window-raisingmechanism, a casing containing the working elements of the motor open atits rear side, and an attaching spider applied to the mounting structureof the 'door and to the open rear side of the motorcasing and forming asupport for the rear end of the motor-shaft.

2. An electric Window-operating device for automobiles, comprising asubstantially bowl-shaped casin open at its rear side and having adetachable closure at its front side, electric motor elements containedwithin said casing and including a motor-shaft adapted for operativeconnection to the actuating 59 spindle of the window-raising mechanism,

and an attachment s ider applied to the mounting structure of the doorand to the open rear side of the casing and forming a support for therear end of the motor-shaft, the closure at the front side of saidcasing forming a bearing for the front end of said shaft.

I 3. An, electric window-operating device for automobiles, comprising areversible mo- 60 tor including a shaft adapted for operative connectionto the actuating spindle of the vindow-raising mechanism, a casingcontaining the working elements of the motor open at its rear side, thefront end of the motorshaft extending through said casing and casing andincluding a motor-shaft adapted for operative connection to theactuating spindle of the window-raising mechanism,
